Ji'nan Times reporter Liu Biao
the influence of the wine and ghost wine plasticizer is still continuing. In May last year, some of the beverages in Taiwan were also exposed to plasticizers. It was understood that when Taiwan drinks were explosive containing plasticizers last year, Taiwan media reported the news that a 8 - month - old male baby in Taiwan was only 1 centimeters long, less than 1/3 of the same age boy, and his mother drank pearl milk tea every day during pregnancy. Beverages and spirits have been caught in the "plasticizer scandal", causing people to worry about the safety of plastic products and containers.
insulation is difficult but the more hot and toxic
reporter has learned that the plasticizer contained in food may sometimes not be artificially added, but inadvertently. In daily life, plasticizers are hidden around us. It is really difficult to completely insulate them. Hao Aiyou, a doctor of chemistry and chemical engineering, Shandong University, who has been engaged in the research of plasticizer and other related fields, told reporters that the plasticizer is a derivative of phthalic acid and two formic acid, which is widely used in plastic products because of its low price.
it is introduced that polyethylene, polypropylene, polyvinyl chloride and other plastics have some brittleness, which is not conducive to processing and use. Therefore, some auxiliaries should be added to the processing, and the plasticizer is a good auxiliary. Adding this kind of material in the plastic processing can make it more flexible and easy to process. Plastic products commonly used in daily life usually contain plasticizers. If the recycled plastic is reproduced, plasticizer content will be even higher.
generally, the dissolution rate of plasticizer is positively correlated with temperature. The higher the temperature is, the more easily the plasticizer in the plastic products can melt into the beverage food, such as mineral water, and the water becomes "poisonous" if the temperature rises, the more the temperature is, the higher the temperature, the higher the temperature, said Zhu Yanming, the director of the Ji'nan Food Industry Association, so it is not advisable for some people to release water in the car in summer.
in addition, in cosmetics, some nail polish plasticizer content is very high, adding the plasticizer nail polish film is better, looks also more lubricated with the texture, winter is not easy to crisp, the summer is not easy to stratification. Eating food with fingernail polish hands is a risk of sending plasticizers into the mouth.
want to avoid, see the number of plastic bottles at the bottom of the number
although the plasticizer is widely used in plastic products, but according to the demand is different, the amount is not the same, in which polyvinyl chloride (PVC) material made of plastic products, the amount of plasticizers is relatively much, the use must be cautious. But there are tricks. Plastic products are usually marked with triangular symbols. There are some numbers ranging from 1-7, which can be used to guide the use.
unfortunately, reporter survey found that in daily life, fewer people pay attention to these figures. "The number is so small, not careful to see, but too professional, and too professional, if the number has a meaning, why can not be marked in a waking place?" in the supermarket random interview, the citizen Sue said, although he did not know the meaning of the number, but since the number has a meaning, what can not be shown on the bottle, let the consumer More clear?
the reporter noticed that most of the common mineral water, juice and other drinks in the life of the plastic bottle bottom triangle inside the numbers are mostly "1", and have the words of PET. In the bottom of the bottled edible oil bottle, the number inside the triangle is "1" or "2", and the words "PET" or "PETE" are below the triangle. The number of cosmetic plastic bottles is mostly "2" and is marked with the word "HDPE". Some plastic kettles, bottled mineral water bottom most of the bottom of the standard is "7", and the individual standard is "58", the following "PC", and some plastic lunch boxes at the bottom of the number is mostly "7". There are also no signs at the bottom of the plastic products.
reporters asked 10 consumers, of whom 8 said they did not know what Arabia numbers and "PET" letters represented. "But I suggest that consumers should know what these numbers and letters represent from the perspective of their health, and then guide consumption." Liu Qingnian, Deputy Secretary General of the Ji'nan food industry association and engineer, said that if you want to avoid the plasticizer, you should see the number of the bottom of the bottle.
